EDF has announced that the Hinkley Point C nuclear power project currently being developed in Somerset (United Kingdom) will require an additional investment of £1.9bn (€2.14bn) to £2.9bn (€3.3) for completion, due to challenging ground conditions making earthworks more expensive than anticipated, revised action plan targets and extra costs to implement the completed functional design. The new cost of the power plant will now range from £21.5bn (€24bn) and £22.5bn (€25.4bn). The Hinkley Point C project is developed by EDF, CGNPC and CNNC and will consist of two 1,630 MW Areva EPR reactors (namely Hinkley Point C-1 and Hinkley Point C-2). Since July 2017, the risk of a deferral in the delivery (COD) of the project is estimated at 15 months for Unit 1 (commissioning in 2027 instead of late 2025) and 9 months for Unit 2 (commissioning in 2027).
